The correct answer is B. HP P2000 G3 SAS MSA Controller. The HP P2000 G3 SAS MSA Controller uses a direct-attached storage protocol that has no network transport layer and therefore cannot perform remote snapshot replication between sites.
Question
Your customer has two sites and you have selected to use the HP P2000 MSA storage array as their storage solution. You plan to implement remote snapshot replication between these sites. Which controller does not support this functionality?
Options
- AHP P2000 G3 iSCSI MSA controller
- BHP P2000 G3 SAS MSA Controller
- CHP P2000 G3 Fibre Channel MSA Controller
- DHP P2000 G3 MSA FC/iSCSI Combo MSA Controller

Why each option
The HP P2000 G3 SAS MSA Controller uses a direct-attached storage protocol that has no network transport layer and therefore cannot perform remote snapshot replication between sites.
The HP P2000 G3 iSCSI MSA Controller supports remote snapshot replication over standard IP networks, enabling site-to-site data replication.
The SAS protocol is designed exclusively for direct-attached, short-distance storage connectivity and does not provide a network fabric over which snapshot data can be replicated to a geographically remote site. Remote snapshot replication requires a network-capable protocol such as iSCSI or Fibre Channel to transport data between sites across a WAN or SAN. All other P2000 G3 controller variants use network-based protocols that natively support remote replication, making the SAS controller the only one that cannot fulfill this requirement.
The HP P2000 G3 Fibre Channel MSA Controller supports remote snapshot replication across FC SAN fabric connections between physically separate sites.
The HP P2000 G3 FC/iSCSI Combo Controller supports remote snapshot replication using either Fibre Channel or iSCSI, providing flexible connectivity options for inter-site replication.
